Canine forum?

I have a friend whose dog has just been diagnosed with diabetes. He is looking for a group similar to this that deals with canine diabetes. He hasn't had much luck just searching the internet. Does anyone here know of a group that he can get in contact with?

This forum has helped me so much with Zoey. I would like him to be able to take advantage of the knowledge and experience of others who have or have had diabetic dogs.
